Paradox breaks the mold that the other FGs have made in that it has more than 12 copies of non-tower cards. For consistency and for a precedent to develop new FGs the excess cards should be removed. The other choice is, of course, to forgo the rule altogether and allow all FGs to have more than 12 copies of cards.
